FWIW, On Bonding, Per the Prosine manual:
“AC Output Neutral-to-Ground Bonding System,
The PROsine provides an installer-defeatable system that automatically connects the neutral conductor of the inverter AC output circuit to safety ground (“bonding” it) during inverter operation, and disconnects it (“un-bonding” it) when the PROsine has connected to AC shorepower. This system is designed to conform to installation codes that require single-phase AC sources such as inverters and generators to have their neutral conductors tied to ground in the same way that the neutral conductor from the utility is tied to ground.
These same codes specify that the neutral can only be connected to ground in one place at any one time. Any AC source feeding the PROsine is required to have its neutral already connected to ground. Therefore, to keep from connecting the neutral to ground in a second place, the PROsine transfer relay breaks its own neutral ground connection when connected to shorepower….”
Upon edit, the ‘installer-defeatable system’ option mentioned in the first paragraph above does not exist…So much for manuals…
